 # QGIS-ROS
+
+**Warning: This package is not currently maintained and may not work without some additional technical care. It looks like a newer version of QGIS has changed a bunch of the Python interfaces. Try using QGIS 3.10 or perhaps a bit older. PRs are welcome!**

 A QGIS plugin for interacting with data from ROS topics and bags.

 ## Usage (source)
+
 ```bash
 rosrun qgis_ros start_qgis_ros
 ```
 
 Once QGIS is loaded, navigate to Plugins -> Installed -> and enable QGIS_ROS with the checkbox. You only need to do this once.
 
 With custom ROS Message Translators:
+
 ```bash
 export QGIS_ROS_EXTRA_TRANSLATORS='custompythonmodule.translators'
 rosrun qgis_ros start_qgis_ros
 ```
 
 ## Usage (docker)
+
 It can often be very tricky to comfortably resolve all dependencies in your workspace because of the combination of ROS1, Python3, GDAL 2, and QGIS.
 
 It uses a lazy/reckless way to expose X server to the container. For alternatives, check out the [ROS Docker GUI Tutorial][2].

 To use extra translators, you'll need to mount a volume with them and/or extend the image.
 
 ## ROS Message Translators
+
 QGIS is able to read and write data from hundreds of formats and sources by translating these formats into a common in-memory format. In order to represent ROS messages in this format, we target common interchange formats (GeoJSON and GeoTIFF) to make it easy to extend. If you want to make use of a custom ROS message type, all you have to do is:
 
 1. subclass `qgis_ros.core.translators.Translator`

 ## Troubleshooting
 
 ### My topic does not appear in the list of topics
+
 Only topics that have ROS Message Translators will appear. Not every message has been implemented. If your message is custom, look above for how to create a custom translator. If it is standard to ROS, create an issue or raise a Pull Request with a new one.TODO: add an example to the ROSCon presentation repository and link here.

 ## Contributions
+
 Contributions are appreciated. Please open a pull request.
 
 Developers will notice that `camelCase` is being used in Python. This may seem unusual, but PyQT and QGIS both use `camelCase`.So we follow that standard in accordance with PEP8.

 Being a robogeographer is a lonely life. If there are any others out there, don't hesitate to say hi!
